Steel Making, Metal Processing and Water Purification Metallurgy refers to the process of extracting metals from their ores and altering the metals for use. Metallurgical coal is used in these processes and is distinct from thermal coal that is mainly used in power generation. As a result of its attributes, metallurgical coal trades at prices substantially higher than thermal coal …

Use Of Silicon Aluminium The ability of silicon to improve the strength of aluminium alloys has far reaching consequences for the transport industry. Aluminium alloys are light, yet strong and replace heavier cast iron components. Car wheels, cylinder heads, and engine blocks are routinely seen made from aluminium alloys. Weight reduction in automobiles decreases fuel consumption, which in turn reduces …

Refining Silicon Silicon dioxide (SiO2) is the most abundant mineral in the earth’s crust.  The manufacture of the hyperpure silicon for photovoltaics occurs in two stages. The oxygen is removed to produce metallurgical grade silicon. It is further refined to produce semiconductor grade silicon. An intermediate grade with impurity levels between metallurgical silicon and semiconductor grade silicon is often termed …

Although commonly referred to as silicon metal, silicon (symbol Si) is semi or non-metallic, and is sometimes called a metalloid. Pure silicon is very rarely found in nature, and it is usually found as a constituent of silicon dioxide (silica or quartz) and silicate minerals, such as feldspars. In terms of mass, silicon makes up about 26% of the Earth’s …
